OK - it's not quite completed but darned close.
I got 2 of these chairs from my work for free - I'll post later the original fabric, but trust me that the red, magenta, and purple weave was hideous.
I took apart 1, and it's been sitting in pieces all over my house for a year. I keep saying I'll reupholster it, but I didn't have any inspiration AND hadn't bought any foam.
Well I finally blew $40 on 3" super-dense foam for both chairs, and pieced together a seat out of vinyl remnants from Joanns. I am surprised my Kenmore puts up with me, that vinyl is TOUGH. I have gone through several jeans needles already, but haven't broken thread. (I LOVE you Gutermann!!)
Here is where I'm at. All I need is my parents to bring the upholstery stapler to my house so I can attach the flaps of white. It is very comfy. I'm going to do the other chair too, not *matching* but *coordinating*. (Because I don't want the pressure of trying to make two identical items.) I'm also going to make some throw pillows with the spare foam, maybe with koopa troopas on them or something? Some sort of nintendo something, that I know.
And, credit where credit's due...I was inspired by this awesome post:
p.s. do not look at my linoleum if you value your eyesight.
UPDATE: I finished it today. Used the VERY SCARY hydraulic stapler to attach everything. It is delightfully comfy. If ever you decide to do something like this yourself - splurge and spend the extra $4 a yard on the high-density foam. SOOO worth it.
And another pic for those of you who wanted to see the bottom.
